The therapeutic efficacy of CO_2 fractional laser with liquid nitrogen refrigeration in the treatment of clavus

目的:评价点阵CO_2激光联合液氮冷冻治疗鸡眼的临床疗效。方法:85例鸡眼患者随机分为两组:治疗组43例,给予点阵CO_2激光联合液氮冷冻治疗;对照组42例,单用液氮冷冻治疗,10日1次,共治疗3次。结果:治疗组与对照组痊愈率分别为90.70%和52.38%,有统计学意义(P<0.01);治疗组与对照组复发率分别为2.56%和9.09%,无统计学意义(P>0.05)。结论:点阵CO_2激光联合液氮冷冻治疗鸡眼安全有效。

Objective： To assess the clinical efficacy of CO2 fractional laser combined with liquid nitrogen refrigeration in the treatment of clavus. Methods： Eighty-five patients with clavus were randomly divided into two groups： 43 patients in treatment group were treated with CO2 fractional laser combined with liquid nitrogen refrigeration and 42 patients in control group were treated with liquid nitrogen refrigeration alone. The treat-ment was one time every 10 days, for 3 times. Results： The cure rates in treatment group and control group were 90.9% and 52.3%, with a significant difference （P〈0.01）. The recurrent rates in treatment group and control group were 2.56% and 9.09%, with no significant difference （P〉0.05）. Conclusion： CO2 fractional laser combined with liquid nitrogen refrigeration is effective in the treatment of clavus.
